In vitro performance in cotton plants with different genetic backgrounds: the case of Gossypium hirsutum in Mexico, and its implications for germplasm conservation
Axel Tiessen –– Possibly one of the first reports that the presence of transgene can indeed influence the in vitro performance of a plant. This effect could not be expected from the known function of the inserted gene sequences. Apparently, the effect of plant transgenesis is not always predictable using prior molecular knowledge.
Stoichiometric ratios support plant adaption to grazing moderated by soil nutrients and root enzymes
Julin Maloof –– By showing that grazing differentially affects nutrient accumulation per species and that this correlates with difference in relevant enzyme activities the authors uncover a potential mechanism underlying resilience to grazing.
Water permeability/impermeability in seeds of 15 species of Caragana (Fabaceae)
Isabel Larridon –– The authors provide new information about species not previously studied.
Heracleum sosnowskyi seed development under the effect of exogenous application of GA3
Axel Tiessen –– Gibbereline hormone application reduced the germination of H. sosnowskyi seed from 98.0% (control) to 16.5% (GA3 concentration 0.43 mM). The exogenous application of GA3 could be used to inhibit the spread of this invasive plant (Sosnowsky’s hogweed)
Promotion of growth and metal accumulation of alfalfa by coinoculation with Sinorhizobium and Agrobacterium under copper and zinc stress
Marcia Marques –– The article contributes to a better comprehension about interactions between two microorganisms ifor promotion of a more efficient phytoremediation of soils contaminated by toxic metals.
Identification and comparative analysis of the CIPK gene family and characterization of the cold stress response in the woody plant Prunus mume
Tatiana Tatarinova –– Analysis of molecular mechanisms of stress response is important for plant science and biology in general.
Seed survival of Australian Acacia in the Western Cape of South Africa in the presence of biological control agents and given environmental variation
Curtis Daehler –– The authors present quantitative data on impacts of biocontrol agents on several Acacia species in South Africa; contrary to prior reports or assumptions, their data suggest seed-feeding control agents are not decreasing Acacia populations
Biomass estimation equations for mesquite trees in the Americas
Gerard Lazo –– As it becomes more important to understand our ecosystem, this presentation tested different algorithms known to date and attempts to describe the utility in characterizing biomass. This presents a case for future discussions to evolve measurements-for-use utility.
Selection of reference genes for quantitative real-time PCR analysis in cucumber (Cucumis sativus L.), pumpkin (Cucurbita moschata Duch.) and cucumber–pumpkin grafted plants
Gerard Lazo –– As genomes become available the ability to fine-tune gene tracking becomes more important. As this is involves grafted material, the ability to monitor genome contributions appears useful; perhaps there may be something here in distinguishing gene expression in grafted vs. polyploid environments.
Identification and expression analysis of the GDSL esterase/lipase family genes, and the characterization of SaGLIP8 in Sedum alfredii Hance under cadmium stress
Gerard Lazo –– Bioinformatic analysis followed-up by functional testing presents a clear case for future gene-candidate testing in developing strategies for phyto-remediation.
